DESCRIPTION AND SPECIFICATIONS
1.1 FEATURES AND APPLICATIONS
The Model 1054B Microprocessor Analyzers, with the appropriate sensors, are designed to continuously meas­ure and control pH, ORP, conductivity, resistivity, ratio, percent concentration, dissolved oxygen, ozone or total free chlorine in industrial and municipal processes.
The Model 1054B Conductivity Resistivity Analyzers are housed in a NEMA 4X (IP65) weatherproof, corro­sion-resistant, flame retardant enclosure suitable for panel, pipe or wall mounting. All functions are accessed through the front panel membrane keyboard which fea­tures tactile feedback. Measurement data may be read at any time. However, settings may be protected against accidental or unauthorized changes by a user selectable security code. The display indicates the measured value in engineering units as well as temperature, alarm status, hold output and fault conditions.
The 1054B transmits a user selected isolated current output which is continuously expandable over the meas­urement range for either direct or reverse action and can be displayed in milliamps or percent. Output dampening of 0-255 secs. is user selectable.
The output and relay default settings are user selec­table for hold or fault mode operation. The hold output function allows manual control during routine sensor maintenance.
Continuous self diagnostics alert the operator to faults due to analyzer electronics, integral RTD failures, open wiring and process variable range problems. In the event
of a fault condition or hold mode diagnosed by the ana­lyzer, the output will be set to a preset or last process value and the relays will be set to their default settings.
Dual alarms are a standard feature on the Model 1054B and are programmable for either high or low oper­ation. Alarm 2 may be programmed as a fault alarm. Both alarms feature independent setpoints, adjustable hysteresis and time delay action. The time delay is con­venient when an alarm is used for corrective action, such as shutting down a demineralizer for regeneration. Time delay will ignore a temporary breakthrough and prevent shutting down a de-mineralizer unit prematurely. A dedi­cated interval timer with relay is also provided.
Automatic neutral salt cation correction temperature compensation is standard. The process temperature is accurately measured by an integral RTD in the sensor assembly and is read on the display in °C. For greater accuracy, the temperature indication may be standard­ized to the process temperature.
Calibration is easily accomplished by entering the cell calibration constant (shown on the sensor tag) via the 1045B’s keypad. Standardization can also be made with the cell in process of known conductivity (resistivity).
The Model 1054B Microprocessor Analyzer comes standard with an LCD display. An LED display is avail­able as an option.
SPECIAL TEMPERATURE COMPENSATION for low conductivity (high resistivity) meas-
urement.
SELF DIAGNOSTICS with a user selectable fault alarm.
KEYBOARD SECURITY is user selectable.
NO BATTERY BACK-UP REQUIRED. Non-volatile EEPROM memory.

MODEL 1054B LC SECTION 1.0
DESCRIPTION AND SPECIFICATIONS
The Model 1054B Low Conductivity Analyzer measures 0-20 µS/cm or 0-18.3 megohm/cm. It is commonly known that in measuring the resistivity or conductivity of ultrapure water, temperature compensation is very criti­cal. The temperature coefficient of ultrapure water depends both on the temperature and resistivity/conductivity of the water being tested. The Model 1054BLC incorporates a 1000 ohm RTD for temperature measurement, and is capable of measuring and displaying temperature accurately within ± 0.1°C. Temperature measurement is resolved to 0.025°C and this precise measurement is used in the analyzer’s temperature compensation calcula­tion. Temperature compensation formula appropriate for water contaminated with minute quantities of sodium chloride is user selectable. For Cation resin columns, a formula specific to the characteristics of pure water con­taminated with minute quantities of hydrochloric acid is user selectable.

INSTALLATION
2.1 GENERAL. This analyzer's enclosure is suitable
for outdoor use. However, it should be located in an area where temperature extremes and vibrations are minimized or absent. Installation must be performed by trained technician.
2.2 UNPACKING AND INSPECTION. Inspect the analyzer for shipping damage. If damaged, notify the carrier immediately. Confirm that all items shown on the packing list are present. Notify Rosemount Analytical if items are missing.
2.3 MECHANICAL INSTALLATION. Select an instal­lation site that is at least one foot from any high volt­age conduit, has easy access for operating personnel, and is not in direct sunlight. Mount the analyzer as fol­lows:
1. Remove the four screws that secure the rear cover of the enclosure.
2. Remove the four screws holding the front panel assembly of the enclosure and carefully pull the front panel and connected printed circuit boards straight out.
3. Follow the procedure for the appropriate mounting configuration: Section 2.3.1 for panel mounting, Section 2.3.2 for wall mounting, Section 2.3.3 for pipe mounting.
2.3.1 Panel Mounting (Standard). The Model 1054B
is designed to fit into a DIN standard 137.9 mm X
137.9 mm (5.43 inch X 5.43 inch) panel cutout
(Refer to Figure 2-1 and Figure 2-2).
1. Prepare the analyzer as described in Section 2.3.
2. Install the mounting latches as described in Figure 2-2 (latches are shown oversize for clarity). If the latches are not installed exactly as shown, they will not work correctly. The screws provided are self-tapping. Tap the screw the full depth of the mounting latch (refer to side view) leaving a gap greater than the thickness of the cutout panel.
3. Align the latches as shown and insert the analyz­er enclosure through the front of the panel cutout. Tighten the screws for a firm fit. To avoid damag­ing the mounting latches, do not use excessive force.
4. Replace the front panel assembly. Circuit boards must align with the slots on the inside of the enclo­sure. Assure that the continuity wire is connected to the rear cover and the interface board’s closest mounting screw. Replace the door and four front panel screws.
2.3.2 Wall Mounting Plate with Junction Box
(P/N 23054-01). Refer to Figure 2-3 and Figure 2-4.
1. Prepare the analyzer as described in Section 2.3.
2. Mount the junction box and bracket to the analyz­er with the hardware provided. All wiring can be brought to the terminal strip prior to mounting the analyzer.
3. Place the metal stiffener on the inside of the ana­lyzer and mount the two 1/2 inch conduit fittings using two each weather seals as shown. Mount NEMA 4X conduit plug (included) into center con­duit hole.
4. Mount the analyzer to the junction box using the 1/2 inch conduit fittings.
5. Complete wiring from the analyzer to the junction box (Refer to Figure 2-4).
NOTE
Run sensor wiring out of the left opening (From front view) to junction box. All others out right opening to junction box.
2.3.3 Pipe Mounting (P/N 23053-00). The 2 inch pipe
mounting bracket includes a metal plate with a cutout for the analyzer (Refer to Section 2.3 for mounting the analyzer into the plate). Mounting details are shown in Figure 2-5.
2.4 ELECTRICAL WIRING. The Model 1054B has
three conduit openings in the bottom rear of the ana­lyzer housing which will accommodate 1/2 inch con­duit fittings. From the front view, the conduit opening on the left is for sensor wiring; the center is for signal output and the opening on the right is for timer, alarm, and AC connections. Sensor wiring should always be run in a separate conduit from power wiring. AC wor­ing should be 14 guage or greater.

MODEL 1054B LC SECTION 2.0
INSTALLATION
NOTE
For best EMI/RFI protection the output cable should be shielded and enclosed in an earth grounded rigid metal conduit. When wiring directly to the instrument connect the output cable’s outer shield to the transmitter’s earth ground via terminal 8 on TB3 (Figure 2-6). When wiring to the wall mounting junction box connect the output cable’s outer shield to the earth ground terminal on TB-A (Figure 2-4).
The sensor cable should also be shielded. When wiring directly to the instrument con­nect the sensor cable’s outer shield to the transmitter’s earth ground via terminal 8 on TB-2 (Figure 2-6). If the sensor cable’s outer shield is braided an appropriate metal cable gland fitting may be used to connect to braid to earth ground via the instrument case. When wiring to the wall mounting junction box connect the sensor cable’s outer shield to the earth ground terminal on TB-A (Figure 2-4).
The user must provide a means to disconnect the main power supply in the form of circuit breaker or switch. The circuit breaker or the switch must be located in close proximity ot the instrment and identified as the discon­necting devie for the instrument.
2.4.1 Power Input Wiring. The Model 1054B can be configured for either 115 VAC or 230 VAC power.
Connect AC power to TB1-8 and -9 (115 VAC) or TB1­7 and -8 (230 VAC) ground to the ground terminal at TB3-8 (refer to Figure 2-6).
CAUTION
The sensitivity and stability of the analyzer will be impaired if the input wiring is not grounded. DO NOT apply power to the analyzer until all electrical connections are verified and secure. The following precau­tions are a guide using UL 508 as a safe­guard for personnel and property.
1. AC connections and grounding must be in compli­ance with UL 508 and/or local electrical codes.
2. The metal stiffener is required to provide support and proper electrical continuity between conduit fittings.
3. This type 4/4X enclosure requires a conduit hub or equivalent that provides watertight connect, REF UL 508-26.10.
4. Watertight fittings/hubs that comply with the requirements of UL 514B are to be used.
5. Conduit hubs are to be connected to the conduit before the hub is connected to the enclosure, REF UL 508-26.10.
6. If the metal support plate is not used, plastic fit­tings must be used to prevent structural damage to the enclosure. Also, appropriate grounding lug and awg conductor must be used with the plastic fittings.
2.4.2 Output Wiring. The signal output and alarm
connections are made to terminals 1 through 6 of TB1 and TB3-1 and 2. (Refer to Figure 2-6).
2.5 Sensor Installation. The Model 1054BLC is
designed to work with sensor Models 441, 455, and Endurance line. These cells are of stainless steel con­struction with titanium-palladium electrodes. Standard 3/4 in. NPT mounting threads are provided on Model 441, 1/4 in. FPT on the Model 455. In these cells the RTD temperature compensator is located within the center element where it makes optimal thermal con­tact with the process stream. The cells are equipped with integrally connected cable (10 ft standard). Refer to Figure 2-6 for sensor wiring.
For Endurance line sensors, please refer to the Endurance instruction manual.
2.5.1 Cell Location.A mounting location should be
chosen to meet the following considerations:
1. Avoid dead ends or pipe stubs or any location where circulation might be poor.
2. If velocity is very low, mount the cell so that the stream is directed against the end of the elec­trodes and the water will flow between the elec­trodes.
3. Be sure that the pipe is full of water and that the cell is completely immersed up to the pipe threads.
4. Cell mounting vertically downward is not recom­mended due to possible air entrapment.

2.5.2 Model 441 Installation. The Model 441 should be screwed gently into a 3/4 in. NPT female pipe fitting using a parallel jaw wrench. The stain­less steel threads should be coated with a suitable pipe compound which will act to seal the threads, and prevent the need for overtightening. Teflon thread tape is recommended for this purpose. After the cell is installed, the cell cable should be support­ed in such a way as to reduce strain and minimize the danger of the cable becoming snagged and pulled from the cell.
2.5.3 Model 455 Installation. The Model 455 is pro­vided with 1/4 in. SwagelokTMtube fittings. These are suitable for direct insertion into 1/4 in. O.D. sam­ple lines. If connection to the plastic tubing is
desired, the SwagelokTMfittings may be removed and replaced with 1/4 in. FPT - hose barb fittings. Fitting threads should be coated with a suitable pipe compound which will act to seal the treads, and pre­vent the need for overtightening. Teflon thread tape is recommended for this purpose. After the cell is installed, the cell cable should be supported in such a way as to reduce strain and minimize the danger of the cable becoming snagged and pulled from the cell.
2.5.4 Endurance Line Installation. Please refer to the Endurance line instruction manual. Other installation information can be found in Figures 2-4 and 2-6.
